where is the access opening to trailer umbilical?

where do I gain access to the conecting point of the trailer umbilical on my 62' Ambassador? I can not find any access panel anywhere under or in front of the trailer. I even looked inside for one but did not find it. I want to put a new 7 wire umbilical cord on it but dont know where it connects inside with the rest of the wireing or where the distibution point is. HELP ME PLEASE SOMBODY!

On my 63 that was built in Jackson Center, there was a small what looked like a patch riveted to the bottom of the right front side of the underbelly. It ws only about 3 X3 but did give me access to that connection. There was nothing else there but the terminated wires. I can not remember but, I think they were just wing nuts or splices.

... front curb side corner under the belly pan. I just was rewiring mine and good luck with getting the new pigtail through the frame. I ended up running it on the inside of the A frame and then into the belly pan. When you get in there you will find four thin red wires. They all look the same, but will have knots tied into them. I am not sure what the wire with no knot does, but the one wire with one knot is the left turn signal. Two knots is the right turn signal. Three knots is running lights. Re wiring the pigtail is a frustrating task. I had to pull my battery and make two leads as to test things as I went. Be sure to create a new ground wire while you are in there. With these 12 volt systems you can never have it grounded enough.
